Title

Belief function model for information retrieval

Source

Journal of the American Society for Information Science. 44(1993) no.1, S.10-18

Year

1993

Abstract

Describes the belief function model for automatic indexing and ranking of documents with respect to a given user query. The model is based on a controlled vocabulary, such as a thesaurus, and on term frequencies in each document. Belief functions and query belief function can be defined and the agreement between a document belief function and a query belief function can be computed. Proposes that the set of documents be ranked according to their agreement with the given user query. Demonstrates that the Belief Function Model is wider in scope than the Standard Vector Space Model
